Rare earth element systematics in ancient and modem hydrothermal systems

, 1998
The geochemical significance of on-axis diffuse fluids, in addition to those formed during the waning phases of hydrothermal systems and off-axis crustal ageing processes, has been investigated through a comparison of the rare earth element (REE ...

Single Versus Multiple Intimate Partner Violence Relationships: Current Severity of Psychological Distress Among Romantic Partners

Journal of Clinical Psychology, EarlyView.
ABSTRACT Objective Experiencing multiple relationships with intimate partner violence (IPVRs) in one's lifetime is linked to poorer mental health outcomes. However, associations among multiple IPVRs, depression symptoms, and posttraumatic stress symptoms (PTSS) have primarily been tested with individual women.

Mental health measures among adolescents in 12 low‐ and middle‐income countries: Measurement invariance and cross‐sectional analyses of Disrupting Harm survey data

JCPP Advances, EarlyView.
Abstract Background Nationally representative mental health data in adolescents from low‐ and middle‐income countries (LMICs) are scarce. This study aimed to examine mental health and wellbeing indicators amongst adolescents in 12 LMICs across Eastern and Southern Africa and Southeast Asia. Methods We conducted a secondary analysis of data involving 12,

The role of rare copy number variants in early‐onset depression

JCPP Advances, EarlyView.
Abstract Background Depression is a highly heterogeneous condition. Depression with an onset in childhood and early adolescence has a worse clinical course, is more heritable, and shows a lower genetic correlation with other depression subtypes, than does later‐onset depression.
